NullPointer in toString of PersistentBag
----------------------------------------

                 Key: HHH-5266
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5266
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.2
            Reporter: Jan Stolze


We have created an interceptor which keeps track of changes during a running transaction so in case of a rollback we can log which changes where issued before the rollback is performed. Now we sometimes see in case a rollback is issued the following stacktrace:

exception in interceptor afterTransactionCompletion()
java.lang.NullPointerException

We do not have (at this moment) a clear overview of what has happend and what the exact conditions are for this NPE to occur, but think it is still important enough to report.
